I have noticed that most of the time it is a young kid.
I sometimes just have an inkling, like when I can tell it is just too good to be true, you know? Like the girl who posted the pictures of jumpers saying that was her....
Well my first "lightbulb" moment was the fact that she was supposedly competing at that height in jumpers, but decided to come on a forum to ask for a critique...sure it happens, but not often.
2. The name, it was "horsepony" or something...I would have imagined it to be a bit more realistic or professional.
3. When the poster put a bunch of gibberish like "askjgjksdhgjkds" then said she put the laptop next to the horse and he typed with his nose. Things like that don't happen, who would put an expensive electronic next to a horses face like that? Doesn't happen.
I hope the mods don't get angry at me for mentioning anyone specifically, I'm just letting other posters see what I do.
Oh, not to mention, google has this nifty thing that if you save the image on your computer, go to google images, then upload the picture, it will find the picture's source(if it exists elsewhere). I did that with all three images.
......I have no life, I'm aware.
